Dropbox can't start after I moved hard drive to a new computer.

[rvenes]

Hello!  

I have physically moved my Dropbox hard drive to a new-old computer.  I had this hard drive in my main computer, and now moved it to my 2nd home computer and wanted to install Dropbox there.   The Dropbox folder is located at G:\Work Dropbox on both computers.  I also added a bigger hard drive to my main computer. 

The idea was to install Dropbox with the same path as the old one, so i don't have to download all the data again, but it will not let me start. My main computer runs Windows 11 and the 2nd computer runs Windows 10.  I get this error message when i start the dropobox app after i pointed the path to the dropbox harddrive G:

Hey @rvenes, I hope you're doing well, let's see what we can find! 

As a first step, would you mind trying out these steps provided by my colleague, Nancy? 

If this doesn't work, don't hesitate to let me know. Thank you!

Hey @rvenes - sorry to jump in here, but at this point I'd suggest a clean, advanced reinstall where you'd be able to point your Dropbox folder to your desired drive and select the folders you'd like to be synced on your new computer.

Let us know how it goes!

That worked. 

I had to download the offline installer, because the normal installer didnt want to download for some reason.  I also had to choose  a few days earlier version of the dropbox installer.   But its working now, and i assume it will autoupdate to the lastest one.

Awesome news @rvenes!

If you need anything else, we'll be one post away, so let us know! 😎
